Rubber pavements, apparently, have already been introduced to parts of Shanghai and Chicago, and could be introduced en masse in Philadelphia:
The main advantage of a rubber pavement is that it is porous, and thereby allows rainwater to percolate through into the groundwater, minimising surface run-off. Rubber pavement also allows air to penetrate into the soil, enabling tree roots to breathe. When the area over tree roots is concreted, the roots become suffocated, and actually spasm upwards to break through the concrete.
The initial costs of laying rubber pavement are currently slightly greater than concrete pavement, but according to Philadelphia councilman Jim Kenney, interviewed on Radio 5's 'Up all Night', it lasts longer than concrete pavement, and can be made from the recycling of old car tyres, so ultimately provides a cost saving.
